Communications Specialties, Inc. (CSI) has broken new ground with the introduction of the industrys first ?drop-and-repeat fiber optic receivers for RGB and Stereo Audio. The addition of the 7223, 7225 and 7227 models to the Pure Digital Fiberlink 7220 Series marks the latest expansion of the only complete family of all digital RGB and audio over one fiber solutions. Offering a combination of multiple baseband outputs and optical loop-through capabilities, the three new models further extend the point-to-multipoint distribution options provided by the 7220 Series. All are compatible with any transmitter unit within the 7220 Series. General descriptions are as follows:

7223 Receiver: Offers four baseband outputs of high-res RGB, each with stereo audio

7225 Receiver: Offers one baseband output of high-res RGB with stereo audio, plus one optical loop-through output for drop-and-repeat configurations

As part of the 7220 Series, these units operate at 1310 nm and work with either single mode or multimode fiber. Optical signals are transmitted and received over a single fiber. Video resolutions supported include VGA, SVGA, XGA and WXGA (640 x 480 up to 1366 x 768), plus HDTV resolutions of 480p, 720p and 1080i (RGBHV format only). The receivers require no adjustments, equalization or de-skewing and use all digital processing. Only a box version is available; power supply is sold separately.

The expanded 7220 Series is ideal for use in applications such as digital signage, broadcast or corporate studios, auditoriums, stadiums and theaters, airport or transportation hubs, distance learning, and surgical or medical imaging. The new receiver models are compatible with Pure Digital Fiberlink optical distribution amplifiers (8000 or 8100 Series), allowing for extremely complex signal distribution options.
